(Optional) Configuring a Receiving Device to Ignore Remote Loopback Requests

Context

If an interface is in loopback state, the interface loops back all received traffic, causing service interruption and allowing attacks. To solve these problems, configure the local device to ignore remote loopback requests.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The interface view is displayed.
Run efm loopback ignore-request
The interface is configured to ignore remote loopback requests.

By default, the local device processes remote loopback requests.
